First sensor 412 is identical in spring material receiving mechanism 410, is the infrared distance sensor of model LTDM18NO, and second passes
Sensor 472 is electrically connected on rotating disc 300, and second sensor 472 detects and the corresponding bolster stake of vacancy testing agency 470
There are when valve spring 101 on 312, rotating disc 300 shuts down, for the construction quality for relatively rotating disk 300, the second sensing
Device 472 is prior to first sensor 412, it is possible to understand that ground, in the corresponding spring carrier 310 of vacancy testing agency 470 if it exists
Valve spring 101, when rotating disc 300 shuts down, first sensor 412 no longer plays control action to rotating disc 300.
The specific assembling process of above-mentioned valve spring 101 are as follows: spring carrier 310 receives gas at spring material receiving mechanism 410
Door spring 101, transport is by being adjusted the direction of valve spring 101 when spring adjustment mechanism 420, so that valve spring
101 unified directions, spring carrier 310 is transported to terminal material receiving mechanism 430 later, is received valve terminal 102, is compressed in spring
The pressure holding of valve terminal 102 is fixed in valve spring 101 at mechanism 440,310 step-operated of spring carrier, is detected in spring
The installation of valve terminal 102 is detected at mechanism 450 to the flatness in valve spring 101, so as to judging valve spring 101 and valve
Terminal 102 assembles effect, after the completion of valve spring 101 detects, by valve spring 101 and valve at spring gripping body 460
The crawl of terminal 102 is transferred in corresponding storing utensil, finally the detection spring carrier 310 in vacancy testing agency 470, so as to
Judge whether vacancy testing agency 470 runs well.
In above-mentioned assembling process, valve spring 101 is transported under the carrying of spring carrier 310 to spring adjustment mechanism
After at 420, adjusts the pusher cylinder 425 on the longwell of pedestal 421 and push down on adjustment framework 422, adjust framework 422 along adjustment
Track 423 persistently moves down, and final adjustment framework 422 and positive stop strip 424 are bonded, and adjusts framework 422 at this time and is provide with to spring carrier
The top of bolster stake 312 in 310, induction cylinder 481 start, and touch sensor 426 declines, and adjusts the touching sense in framework 422
The end face of the valve spring 101 on device 426 and bolster stake 312 is answered to be contacted, 426 basis of touch sensor and valve spring
101 contact area judges the direction of valve spring 101, when touch sensor 426 touches lesser end face, gripper cylinder
427 start, and the adjustment clamping jaw 483 on 427 piston end of gripper cylinder is tightened, and the valve spring 101 on bolster stake 312 is clamped,
The withdrawal of pusher cylinder 425 later, valve spring 101 are detached from bolster stake 312.Touch sensor 426 touches biggish end face
When, the adjustment clamping jaw 483 on 427 piston end of gripper cylinder opens.
Under the driving of pusher cylinder 425, valve spring 101 is detached from bolster stake 312 and rises to initial position, incudes cylinder
481 piston boit is withdrawn, and starts the state of judgement adjustment clamping jaw 483 later, if adjustment clamping jaw 483 is in tightening state, is adjusted
Cylinder 428 is run, and under the driving of adjustment cylinder 428 180 ° of rotations, valve bullet occur in adjustment framework 422 for returning face plate 486
It is upward that spring 101 is changed to big end by small end upwards, later 425 restarting of pusher cylinder, will the driving of adjustment framework 422 to spring
The top of carrier 310, induction cylinder 481 are again started up, and detect the adjustment effect of valve spring 101.
Taking the above-mentioned ideal embodiment according to the present invention as inspiration, through the above description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property range is not limited to the contents of the specification, it is necessary to which the technical scope thereof is determined according to the scope of the claim.
